Understanding Instagram Video Formats

Instagram offers a variety of video formats, each of which has its own unique characteristics and advantages. For marketers creating ads on Instagram, understanding them is crucial. Let’s take a quick look:

Story Videos

Story videos are short clips that disappear after 24 hours. With the maximum length being 60 seconds, they are ideal for quick and engaging content that feels personal and immediate.

Stories are one of the most powerful tools for engagement. They are viewed by over 500 million users daily. Not only that, you can even add polls. questions, and swipe-up links to make it more interactive.

Reels

Reels offer vertical videos up to 3 minutes long. They are designed for creativity and fun, allowing users to add music, effects, and text overlays.

Reels are shown in the Explore section, helping you reach a broader audience beyond your followers.

Feed Videos

Feed videos now encompass longer video content directly in your Instagram feed. Instagram feed videos can be up to 60 minutes long, but you must post them from a desktop, as the mobile app has a 20-minute limit for feed videos.

Feed videos are ideal for sharing detailed content like tutorials, testimonials, or brand stories that will help to increase brand awareness. Besides, many advertisers use this format for repurposing content, which gives new life to existing video content.

Live Videos

Instagram Live allows users to broadcast in real-time for up to 4 hours. This format is ideal for engaging with your audience through Q&A sessions, product launches, or live events.

Instagram Live Video allows real-time interaction with your audience through comments and reactions. This format is also perfect for detailed demonstrations or discussions.

Video Ads

Instagram video ads appear across different placements, including Stories, Reels, and Feed. With the video ads, you can choose the best format that matches your campaign goals. Each ad format has specific guidelines and purposes:

• Story Ads: 5-15 seconds, best for quick, immersive content.
• Reels Ads: Up to 30 seconds, ideal for engaging younger audiences.
• Feed Ads: Up to 60 minutes, suitable for comprehensive storytelling and brand building.

By understanding these video formats, you can tailor your content to fit each platform’s strengths, ensuring your ads are both effective and engaging.

How Long Should An Instagram Ad Be: Factors To Consider

So, how long should Instagram ads be? Before we dive into specific ad length recommendations, here are some influencing factors you should recognize.

Campaign goals

What do you want to achieve with your campaigns? Brand awareness? Website traffic? Sales? Your ideal ad length may differ according to each objective. 

For example, brand awareness ads should be slightly longer. Meanwhile, sales campaigns need to be shorter and more on point. 

Whether you’re optimizing for awareness, engagement, or conversions, understanding your main goal of the campaigns will help you decide the ideal duration for your video ads to capture attention quickly and keep audiences watching til the call-to-action.

Target audience

Your target audience also determines how long your ad should be. Consider their demographics, interests, and online behavior to determine the best duration for your video.

For instance, younger audiences may prefer shorter, trendier content. On the other hand, older demographics often enjoy more detailed explanations.

Ad format

Each Instagram advertisement format (Feed, Stories, and Reels) requires certain specifications about video duration. Viewers also expect something different when viewing content in each placement.

These details will be explained directly in the next section.

Content and storytelling

The complexity of your message and narrative will determine which duration works best. 

The ideal length for a simple product demonstration will differ from that of an emotional narrative-based advertisement.

However, your story should be clear and concise, no matter how long it will be.

Budget

This factor doesn’t directly impact the ideal length, but it’s something you must consider when making ads. 

Shorter ads are often cheaper to create than longer videos, especially for small businesses.

The attention span challenge

According to Dr. Gloria Mark, the Chancellor’s Professor of Informatics at the University of California, the average human attention span has decreased significantly in recent years. 

Users are scrolling more and more quickly, and you have only a few seconds to seize their attention and convey your message. 

This is why you must consider how long Instagram ads are.

Best Length For Different Instagram Ad Formats

With various video formats, it might seem challenging to choose the right duration. However, each format serves a unique purpose and influences how viewers engage with your content. Let’s explore now with the GDT Agency.

Instagram feed video ads

Instagram Feed video ads are integrated directly into a user’s feed, appearing in between content as they scroll. Though a video ad on the Instagram feed can last from 1 second to 60 minutes according to Meta, I recommend no more than 60 seconds. And the best duration is 15 to 30 seconds.

This ensures you can present enough information without shortening the viewer’s focus.

💡 Tips: Capture attention in the first 3 seconds with an effective hook. Add captions to ensure your video accessibility for viewers with sound off.

Instagram Stories video ads

Similar to feed ads, the maximum length for this ad placement is 60 seconds.

Stories can now be used to drive consumers directly to an Instagram shop by using such anticipation-building tips as stickers featuring countdowns to new product drops.

All Instagram Stories video ads are skippable, so be sure to employ a captivating hook in the first seconds of your ad. People watching Stories expect quick and concise content. Several video styles work well here, including live-action and stop-motion. You can employ several CTAs, to which users can respond by swiping up on your ad.

You should make short videos of 15 seconds or less. People watching Stories expect quick and concise content.

💡 Tips: Use vertical format, trending music, along with interactive features, to stop people from swiping right. 

Instagram Reels video ads

According to Meta, an Instagram video ad in Reels format must not exceed 15 minutes. The optimal length to use for Reels ads is under 60 seconds.

Reels offer insights to makers, so you can see what’s working and what isn’t. If scrollers go to the Reels tab, they may stumble upon yours, too, since this page shows many Instagram accounts. Advertisers should focus on making their own and making them seem native to the platform. They can also consider branded content partnerships with current and upcoming Instagram personalities.

For the best results, you should maintain the length between 15 and 30 seconds.

💡Tips: Prioritize entertaining content and use trending audio, because this is what people are looking for there.

Additional Tips To Optimize Instagram Ad Performance

While the ad length plays an essential role, other aspects contribute equally to success. Here are some additional tips for producing successful Instagram video ads:

Apply the 3-second rule

The first few seconds of your videos are critical, according to the 3-second rule.

Start with eye-catching visuals, compelling music, or engaging hooks to grab viewers’ attention at the beginning.

Then, present your key message immediately instead of beating around the bush. 

Use visual storytelling

Visual content works best for Instagram since it is a visual-centric platform.

To present your story effectively, you should select high-quality footage, professional editing, and interesting graphics.

Even short videos can be powerful with striking images.

Add music and sound

Music and sound remain essential to any video. They can quickly create the mood and immerse audiences in the story.

Also, be sure to add captions for viewers who view Instagram with their sound off.

Craft clear calls to action (CTAs)

Every advertisement needs a specific call to action that tells viewers what to do after watching it.

Use a strong CTA to achieve your desired action easily, such as Shop Now, Visit Website, etc.

Experiment with different variations

The best way to determine your ideal video ad length is to test multiple versions.

Track the results and scale up with those ads that generate the best conversions.
